Which situation is represented by P(A ∪ B)? a) Passing both English and Math b)  Passing English or Math 11) Why must P(A ∩ B) be subtracted when computing P(A ∪ B)?  a) To reduce the sample space b) To avoid double counting shared outcomes 12) Which formula correctly represents the probability of the union of two events A and B if A and B are events in the sample space? a) P(A ∪ B) = P(A) + P(B) b) P(A ∪ B) = P(A) × P(B) 13) Why is it important to clearly identify the intersection when illustrating sets using a Venn diagram? a) To know the total number of students b) To avoid counting students more than once 14) In a school program, 3 students are chosen to hold different flags on stage. How many different ways can the 3 students stand in a line?many different ways can the 3 students stand in a line?  a) 3 b) 6 15) Which of the following represents the number of permutations of n distinct objects taken r at a time?taken r at a time? a) 𝑛!/r! b) nPr= n!/(n-r)! 16) A student leader needs 2 officers to arrange the booth design for the Batangas City Division Festival of Talents.

There are 4 volunteers, Anna, Ben, Carlo, and Dana. Which statement best explains how to find the number of possible assignments? a) Use 4C3 because only 3 students are needed. b) Use 4P3 because the roles are distinct and order matters. 18) During a school event, a student committee needs to arrange 4 different band performers in a specific order for the program. If only 3 performers will be chosen for the lineup, how many different possible lineups are there? a) 4 b) 24 19) How many permutations can be formed from 4 different cultural dance props used by Batangas City High School for the Arts in their presentation? a) 12 b) 24 20) A librarian is arranging 3 different research folders on a shelf.
